- Company Profile:
In a photovoltaic device, an n-type dopant, such as phosphorus, that puts an additional electron into an energy level very near the conduction band; this electron is easily exited into the conduction band where it increases the electrical conductivity over than of an undoped semiconductor.
Industry:Energy
A number of photovoltaic modules or panels interconnected electrically in series to produce the operating voltage required by the load.
Industry:Energy
A chemical element (impurity) added in small amounts to an otherwise pure semiconductor material to modify the electrical properties of the material. An n-dopant introduces more electrons. A p-dopant creates electron vacancies (holes).
Industry:Energy
Any one of several components in a photovoltaic system (i.e., array, controller, batteries, inverter, load).
Industry:Energy
A condition that afflicts unused and discharged batteries; large crystals of lead sulfate grow on the plate, instead of the usual tiny crystals, making the battery extremely difficult to recharge.
Industry:Energy
Time when the photovoltaic system cannot provide power for the load. Usually expressed in hours per year or that percentage.
Industry:Energy
SMES technology uses the superconducting characteristics of low-temperature materials to produce intense magnetic fields to store energy. It has been proposed as a storage option to support large-scale use of photovoltaics as a means to smooth out fluctuations in power generation.
